摘要
针对探讨硝胺类发射药的燃速预估模型,在分析硝胺炸药在燃烧分解产物热分解规律的基础上,运用近年来提出的火药燃速预估方法,推导硝铵发射药的燃速公式及压力指数公式。编写硝铵发射药燃速计算软件。在0～400 MPa压力范围内,对硝胺类发射药的燃速进行理论预估,并对3种硝铵发射药的燃烧计算值与相应的试验数据进行比较。分析结果表明,本模型是可行的,适合硝铵发射药的燃速预估。
For analyzing nitramine propellant burning rate predication model, on the basis of analysis of thermal decomposition rule of nitramine explosives combustion decomposition products, use propellant burning rate which was proposed in recent years to derive burning rate formula and the pressure index formula of propellant. Compile burning rate calculation software. Predicate nitramine propellant burning rate in the pressure range of 0-400 MPa, then compare 3 nitramine propellant burning calculation rate with corresponding test data. The analysis result shows that the model is effective which can be used in nitramine propellant burning rate predication.
